I am aware that I am not really addressing the original poster's 
question, but possibly helpful anyway:

I can suggest to consider options where typing a password is replaced by 
presence of something physically, using packages like these:

libpam-biometric / libpam-fprintd - fingerprint
libpam-blue - bluetooth device
libpam-p11 / libpam-pkcs11 / libpam-poldi - smartcard
libpam-ssh-agent-auth - user-to-root access
libpam-yubico / libpam-u2f - hardware dongle
libpam-script - custom routine

I am curious which solutions you end up with for your father, as I am 
working on streamined¹ setup of similar use cases.

I would also appreciate constructive² opinions and feedback from anyone 
experienced with these various ways of sidestepping password-based 
system login.
